Original application led August 15, 1921, Serial No. 492,487, and in Germany November 21, 1919. Divided and this application filed Uctober 28, 1925, Serial No. 65,444.

parts ot the machine situated respectively vabove and below the wire to be moved relatively to each other in such a manner that t-he beams carrylng the breast roller, the table rollers and the suction boxes may be removed laterally out 'from the machine.

ln the drawing several constructional forms of the invention are represented.

Fig. 1 is a side view of the endless wire s ection ot' a paper machine in which'the carrying beams along with the register and suction devices may be lowered a certain distance until rollers mounted on the beams rest on rails, on which the beams with accessory portions may be moved out laterally.

Fig. 2 is a vertical cross section taken through Jche register part ot Fig. 1.

Fig. 3 is a side view of an apparatus similar to that oi' Fig. 1 in which however, the part above Jthe wire may be elevated.V`

Fig. l shows the raising apparatus tor the rear part of the carrying trame.

In` the machine represented in Figs. 1 and 2 the wire parts of the machine commence with the delivery chest 1 with the attached foam laths 2 which by means ot the rod 3 is hung from the carrying frame 4C that is in turn mounted on the pillars 5 and 6. From this delivery chest the paper pulp passes in a known manner to the endless wire 7. The latter is lirst'carrieil by the table rollers 8 which are mounted in the shake rails 15, the rear extremities 16 oi which are pivoted to the carrying beams 18 and are supported at other points in their length and in a manner already known by the shake brackets 17. At the tore-end of the carrying beams 18 there is mounted the horizontally displaceable breast roller 9. At the end of the register part the level roller 19 is arranged and following this are the suction boxes 2O beyond which at'the tar end ot the bearing beam 18 the wire guide roller 36 is mounted. From this latter roller the wire 7 passes round the lower couch roller 10 on which rests the upper couch roller 11 and is then conducted over the wire and tension rollers 12, 13, 111 and 15 back to the breast roller 9. On the wire 7 rest in a manner already .known the deckle-straps 27 which run over the deckle rollers 28 and 37 suspended from the rods 30 and 38 and which may, by means of the d clale carriage 26 wiich is hung trom the trame 4 be displaced laterally.

The beams 18 are providedV with rollers 21 resting on rails 22 that may be taken out. The latter rest on the hoist blocks 23 which may be raised or lowered by means of handwheels 25, and are provided, on the driving side of the machine with vertical arms 241 which serve as lateral fences tor the guiding of the beams 18.

At right angles to the machine and forming a prolongation o1' the rails 22 there rest stationarily on the pedestals 32 the rails 31 (Fig. 2) which can be connected with the rails 22 by means of filling or bridge pieces 33, shown dotted in the ligure, so that the rails 22 and 31 and the bridge pieces 33 may unite to form one continuous travelling way. When it is intended to change the wire, first the inner wire rollers 13 and 15 are placed on hooks 62 provided on the under side of thc "beams 18, the. wire isthen cut through and rolled up in front of the couch rollers and then taken out. hereafter the hoist blocks 23 are by means of the hand wheels 25 so far lowered that the wire can completely clear the delivery chest 1 and the deckle straps 27, whereatter the beams 18 with the entire register and suction parts may be drawn out, on the rails 22, 33 and 31, towards the side of the machine. When this has been effected. the rails 22 are removed from the machine and the new wire is drawn in. The'wire is subsequently with the aid of the two tension rollers 34 and 35 inserted at the tore end, brought into the position indicated in Fig. 1 by the line of dashes, whereupon the rails 22 are again put in the hoisting blocks 23 and the beams 18 with the register and suction devices are again inserted to the machine. The rollers 34C and 35 are then again taken out and the main Wire rollers 12, 13,

14 and l5 instead brought to their working position, the new wire being now ready for use.

Therelative separating motion of the upper and lower parts associated with 'the wire can also be effected by raising the upper part. |'heftwo motions can also be effected simultaneously so that the part situated above vthe wire may be raised, and the part below vnier-.ns .of the screw-shaft 5l and which "ar-ry the rails 22 where-on rest the rollers Q1 oi" the beam-s 18.

f The upperfi'rarnie l is pivoted at its rear end by ineens of the bolts -l-ll to the pillars (i. At the foreend of the it aine is mounted a vworin shaft 40 which can be tfuriied by Ineens of 'the hand wheel Lll, the worrns of which engage with nuts 4t2 on tlieserew spindle -ll mounted o-nith e upper ends of the pillars 5. By rotation these nuts the fore end of the traine' l can be so 'farv elevated that the delivery ch st lsand the deckle straps 27 can clear the wire 7.5 It then further, the brackets 50 bearing the rails Q2 be so far lowered by means oi the screw spindles 5l that the register and suction devices which are carried b v the beams 1S. clear the wire then the beams 18, alo-ng Awith the register and suction devices nia'v .be pulled 4out laterallyv from the machine.

Il it be desired also to raise the rear-end of the bearingr trarne 4, a siinilar apparatus may be arranged here as at the fore-end. In such a ease, as may be seen in Fig. 1l, a worin shaft Il? i Aed with a l'iffind wheel 438 maj,T be ifittedfattlre rear-end 'of the frame il, this shait engaging nuts llt'of the screw spindles .45. In thisA way the carrying-frame lmay be brought to a uniform elevation throughout its length.

rEhe present application is a division of in v copending application Ser. N 492,487, tiled August l5, 1921.
